We will keep on our systematic solution to diagnosing a pool heater by looking at how to proceed read more once the light within the handle pad within the prime within your Sta-Rite pool and spa heater which is labeled “service heater” is lit. (We'll continue together with the assumption that you just know all the things from segment a single.) This time you have got to clear away the sides through the heater before disconnecting electricity into the heater so as to browse the codes on the board attached for the topside. After eradicating the perimeters, you will notice the massive topside that is definitely continue to linked to the heater. Underneath the topside is actually a steel panel that keeps the topside set up. Under this panel you will discover two locking pins (cotter pins). Meticulously take away the two pins and shop them someplace harmless until eventually reassembly. Carefully remove the best and turn it upside down. You will see a light-weight lit within the board you're searching at once you turn the topside around. The light will be beside a code that is certainly published on the board.

The very first code that you're going to see around the still left facet with the board will be PS. Here is the code for your pressure change. We included the pressure change in section one. If this light is lit return to phase one particular and critique that section. If essential follow the directions to switch the force switch.

The following code you may see to the board is HLS. When you have a very controller over the technique you will need to bypass it at the moment. You have got to diligently disconnect the ability in the heater. After you are absolutely sure the electrical power is disconnected, you will have to discover and open the high-voltage cupboard. This cabinet is really a metallic box in the midst of the heater. If you are searching with the cabinet, there is certainly ordinarily a screw around the top rated right facet. Loosen the screw as well as the doorway will swing down toward you. You require for being particularly careful when doing the job during this box and only do this whenever you are guaranteed that the power to your heater is OFF.

You will need to bypass the firewall basic safety interface. To do this you may have to have a brief wire with stab-tab connectors. In the event you possess a controller and it absolutely was effectively mounted the wire can have been left during the box via the tech who put in the controller. If not you must make this jumper wire. At this stage search in the owner's handbook to find the two appropriate pins to connect with. In case you possess a controller or are utilizing a fireman's switch this is where your management needs to be connected. When you have got a controller and it is actually not connected right here, it may be the supply within your complications and either have a very licensed tech correct the issue or proper it your self.

You have to be careful never to place the jumper wire to the electric power terminals otherwise you will destroy your heater by burning up the electronic method. Make use of your manual to find the place the fireman's swap is meant to become connected and punctiliously connect your jumper amongst these terminals. In case you now activate the facility as well as heater performs with no challenges, your trouble lies inside the controller or perhaps the wiring visiting the controller. You have got to problems shoot this technique.

If you continue to provide the very same problem with the heater. (“service heater” light-weight will come on), leave the jumper in place and verify which the pump is on which you might have superior drinking water stream. Be sure yet again using your meter the tension change just isn't cycling. It ought to read for a lifeless small. (See phase 1) With great drinking water flow verified and also the “service heater” gentle on, your dilemma could possibly be among the thermo-regulators while in the basic safety procedure.
